A preferred embodiment of the present invention will be described hereinafter with reference to the drawings.

The construction of the embodiment of a certification system will be described first.

Referring to FIG. 1 of the drawings, there is shown a certification system 10 comprising a master card 21 constituted by an integrated circuit (hereinlater referred to simply as “IC”) card capable of transmitting information to and receiving information from the exterior thereof and carried by a dealer of a vehicle, an IC card 22 capable of transmitting information to and receiving information from the exterior thereof and carried by an owner of the vehicle, an IC card 23 capable of transmitting information to and receiving information from the exterior thereof and carried by a person authorized by the vehicle owner, a certification apparatus 30 equipped with a control unit 31 including a certification unit 31 a for certifying whether or not each of the master card 21, the IC card 22, and the IC card 23 is an authorized device authorized to use components mounted on the vehicle (hereinlater referred to simply as “vehicle-mounted components”) such as, an engine, a door lock, a glove box lock, and a trunk lock. The certification apparatus 30 is fixedly retained on an instrument panel of the vehicle.

The master card 21, the IC card 22, and the IC card 23 have respective identification information, hereinlater referred to simply as “ID” stored therein and constitute storage devices according to the present invention. Here, the IC card certified by the certification unit 31 a using the master card 21 as being the authorized device is called a first card, and the IC card certified by the certification unit 31 a using the first card as being the authorized device is called a second card or a limited card. The master card constitutes a master storage device according to the present invention to be used by the certification unit 31 a to certify the IC card as being the first card. Any one of the IC cards 22 and 23 may be certified as being the first card, the second card, or the limited card, and constitute a authorized storage device, a first authorized storage device, or a second authorized storage device.

The master card 21, the first card, and the second card are authorized to use vehicle-mounted components such as for example an engine, a door lock, a glove box lock, a trunk lock, and the like. The limited card is, on the other hand, authorized to use vehicle-mounted components excluding one or more vehicle-mounted components such as locks of storage rooms, for example, the glove box lock, the trunk lock and the like, which the master card 21, the first card and the second card are authorized to use. This means that the vehicle-mounted components which the master card 21, the first card, and the second card are authorized to use include one or more vehicle-mounted components other than the vehicle-mounted components which the limited card is authorized to use.

The certification apparatus 30 further comprises a blue light emitting diode (hereinlater referred to simply as “LED”) 32 a, a red LED 32 b, a first switch 33 a and a second switch 33 b, both of which are to be pushed by a user, and a permission unit 34 for permitting the vehicle-mounted components to be used.

The control unit 31 of the certification apparatus 30 further includes a communicating unit 31 b for communicating with an IC card such as, for example, the master card 21, the IC card 22, and the IC card 23, inserted into an IC cardholder, not shown, to obtain the ID from the IC card, an internal storage unit 31 c for storing therein ID of the IC card, and storage control means constituted by a registering unit 31 d for controlling the internal storage unit 31 c to have the internal storage unit 31 c selectively store therein and delete therefrom the ID of each of the master card 21, the IC card 22, and the IC card 23, and an information transmitting unit 31 e for transmitting the ID of the first card to be deleted from or stored in the internal storage unit 31 c to the exterior thereof, viz., the Land Transportation Office when the ID is deleted from or stored in the internal storage unit 31 c.

The certification unit 31 a is operative to certify whether or not each of the master card 21, the IC card 22, and the IC card 23 is the authorized device on the basis of the ID of each of the master card 21, the IC card 22, and the IC card 23 obtained by the communicating unit 31 b and the ID stored in the internal storage unit 31 c. Further, the certification unit 31 a is operative to certify that the master card 21 is not the authorized device under the condition that the internal storage unit 31 c has already stored therein the ID of the IC card obtained by the communicating unit 31 b as being the ID of the first card.

The registering unit 31 d is operative to control the internal storage unit 31 c to have the internal storage unit 31 c store therein the ID of the IC card obtained by the communicating unit 31 b as being the ID of the first card only under the condition that the certification unit 31 a certifies that master card 21 as being the authorized device. Further, the registering unit 31 d is operative to control the internal storage unit 31 c to have the internal storage unit 31 c store therein the ID of the IC card obtained by the communicating unit 31 b as being the second card or the limited card only under the condition that the certification unit 31 a certifies the first card as being the authorized device.

The registering unit 31 d is operative to control the internal storage unit 31 c to have the internal storage unit 31 c delete the ID of the second card or the limited card therefrom only under the condition that the certification unit 31 a certifies the first card as being the authorized device. Further, the registering unit 31 d is operative to control the internal storage unit 31 c to have the internal storage unit 31 c delete the ID of the first card therefrom only under the condition that the internal storage unit 31 c has not stored therein the ID of the second card or the limited card and the certification unit 31 a certifies the first card as being the authorized device.

Next, the operation of the certification system 10 will be described hereinlater.

The description hereinlater will be directed to the operation performed by the certification system 10 in the case that the first card is to be registered, for example, after a vehicle is sold to a customer.

It is hereinlater assumed that the internal storage unit 31 c of the certification apparatus 30 stores therein only the ID of the master card 21 before the first card is registered, and the certification apparatus 30 comprises a central processing unit, hereinlater referred to simply as “CPU”, not shown, for controlling the whole processes in the certification apparatus 30.

The IC card is inserted into the IC cardholder by a user (step S41) and the first switch 33 a is held down by the user to assume an on-state uninterruptedly for three seconds (step S42) as will be clearly seen from FIG. 2. The communicating unit 31 b is operated to transmit an ID request signal to the IC card (step S43), and, in return, receive the ID transmitted from the IC card inserted in the IC cardholder (step S44). The communicating unit 31 b forming part of the certification apparatus 30 is operated to obtain, for example, the ID of the master card 21 transmitted from the master card 21 in step S44 in the case that the master card 21 is inserted by the dealer into the IC cardholder in step S41.

The certification unit 31 a forming part of the certification apparatus 30 is operated to judge whether or not the communicating unit 31 b has obtained the ID (step S45). When it is judged by the certification unit 31 a that the communicating unit 31 b has not obtained the ID in step S45, the control unit 31 is operated to have the red LED 32 b illuminate for three seconds to indicate an error message, and this process is terminated (step S46).

When, on the other hand, it is judged by the certification unit 31 a that the communicating unit 31 b has obtained the ID in step S45, the certification unit 31 a is operated to judge whether or not the IC card inserted in the IC cardholder is the master card 21 on the basis of the ID obtained by the communicating unit 31 b and the ID stored in the internal storage unit 31 c (step S47). When it is judged by the certification unit 31 a that the IC card inserted in the IC cardholder is not the master card 21 in step S47, the control unit 31 is operated to have the red LED 32 b illuminate for one second to indicate an error message, and this process is terminated (step S48).

When, on the other hand, it is judged by the certification unit 31 a that the IC card inserted in the IC cardholder is the master card 21 in step S47, the certification unit 31 a is operated to judge whether or not the ID of the first card is stored in the internal storage unit 31 c (step S49). When it is judged that the ID of the first card is stored in the internal storage unit 31 c in step S49, the control unit 31 is operated to have the red LED 32 b illuminate for one second to indicate an error message, and this process is terminated (step S50).

When it is judged that the ID of the first card is not stored in the internal storage unit 31 c in step S49, the certification unit 31 a is operated to certify that the master card 12 is the authorized device (step S51), and the control unit 31 is operated to have the blue LED 32 a illuminate for one second (step S52).

The master card 21 is then ejected by the user from the IC cardholder (step S53) and the IC card is inserted by the user into the IC cardholder within ten seconds (S54). The communicating unit 31 b is operated to transmit an ID request signal to the IC card (step S55), and, in return, receive the ID transmitted from the IC card inserted in the IC cardholder (step S56).

When, on the other hand, the IC card is not inserted into the IC cardholder within ten seconds after the master card 21 is ejected from the IC cardholder in step S53, the control unit 31 is operated to have the red LED 32 b illuminate for three seconds to indicate an error message, and this process is terminated.

When the ID is transmitted from the IC card inserted in the IC cardholder in step S56, the certification unit 31 a forming part of the certification apparatus 30 is operated to judge whether or not the communicating unit 31 b has obtained the ID (step S57). When it is judged by the certification unit 31 a that the communicating unit 31 b has not obtained the ID in step S57, the control unit 31 is operated to have the red LED 32 b illuminate for three seconds to indicate an error message, and this process is terminated (step S58).

When, on the other hand, it is judged by the certification unit 31 a that the communicating unit 31 b has obtained the ID in step S57, the certification unit 31 a is operated to judge whether or not the ID obtained by the communicating unit 31 b is conformable to a predetermined format (S59). When it is judged by the certification unit 31 a that the ID obtained by the communicating unit 31 b is not conformable to the predetermined format, the control unit 31 is operated to have the red LED 32 b illuminate for three seconds to indicate an error message, and this process is terminated (step S60).

When, on the other hand, it is judged by the certification unit 31 a that the ID obtained by the communicating unit 31 b is conformable to the predetermined format, the certification apparatus 30 waits for an operation of the first switch 33 a and the second switch 33 b.

When the first switch 33 a and the second switch 33 b are operated by a user (step S61), the registering unit 31 d is operated to judge whether or not the first switch 33 a is turned on under the state that the second switch 33 b is turned on (step S62).

When it is judged by the registering unit 31 d that the first switch 33 a is not turned on under the state that the second switch 33 b is turned on in step S62, the control unit 31 is operated to have the red LED 32 b and the blue LED 32 a alternately illuminate at one-second intervals for six seconds to indicate an error message, and this process is terminated (step S63). When, on the other hand, it is judged by the registering unit 31 d that the first switch 33 a is turned on under the state that the second switch 33 b is turned on in step S62, the registering unit 31 d is operated to control the internal storage unit 31 c to have the internal storage unit 31 c store therein the ID of the IC card obtained by the communicating unit 31 b as being the ID of the first card (step S64). The master card 21 thus becomes disabled resulting from the fact that the certification unit 31 a does not certify the master card 21 as being the authorized device under the condition that the internal storage unit 31 c stores therein the ID of the IC card as being the ID of the first card.

This means that, in the certification apparatus 30, for example, the IC card 22 of the vehicle owner can be registered as the first card when the IC card 22 is inserted into the IC cardholder in step S54. Additional IC card cannot be redundantly registered as the first card once the IC card 22 is registered as the first card, resulting from the fact that it is judged in step S49 whether or not the ID of the first card is stored in the internal storage unit 31 c.

The information transmitting unit 31 e forming part of the certification apparatus 30 is operative to transmit the ID of the first card to be stored in the internal storage unit 31 c to the exterior thereof, viz., the Land Transportation Office when the ID is stored in the internal storage unit 31 c. This leads to the fact that the certification apparatus 30 can improve the operational efficiency of the Land Transportation Office in terms of registering vehicles.

As described earlier, in the certification apparatus 30, in steps S49 and S51, the certification unit 31 a is operated to certify whether or not the master card 21 is the authorized device on the basis of the ID of the master card 21 obtained by the communicating unit 31 b in step S44 and the ID of the master card 21 stored in the internal storage unit 31 c prior to step S41. In addition, the certification unit 31 a is operated to certify that the master card 21 is not the authorized device under the condition that the ID of the first card is stored in the internal storage unit 31 c. Accordingly, steps S49 and S51 constitute a certification step forming part of a certification method performed by the certification system 10.

Further, in the certification apparatus 30, in steps S44 and S56, the communicating unit 31 b is operated to obtain the ID transmitted from the IC card inserted in the IC cardholder. Accordingly, steps S44 and S56 constitute an obtaining step forming part of the certification method performed by the certification system 10.

Still further, in the certification apparatus 30, the registering unit 31 d is operated to control the internal storage unit 31 c to have the internal storage unit 31 c store therein the ID of the IC card in step S64 obtained by the communicating unit 31 b as being the ID of the first card in step S56 only under the condition that the certification unit 31 a certifies the master card 21 as being the authorized device in step S51. Accordingly, step S64 constitutes a storage step and a storage control step forming part of the certification method performed by the certification system 10.

The description hereinlater will be directed to the operation of the certification system 10 in the case that the second card is to be registered, for example, after a family member or a working staff is authorized by the vehicle owner to use vehicle-mounted components.

It is hereinlater assumed that the internal storage unit 31 c of the certification apparatus 30 stores therein the ID of, for example, the IC card 22 as being the ID of the first card before the second card is registered, and the certification apparatus 30 comprises a central processing unit, hereinlater referred to simply as “CPU”, not shown, for controlling the whole processes in the certification apparatus 30.

The IC card is inserted into the IC cardholder by a user (step S71) and the first switch 33 a is held down by the user to assume an on-state uninterruptedly for three seconds (step S72) as will be clearly seen from FIG. 3. The communicating unit 31 b is operated to transmit an ID request signal to the IC card (step S73), and, in return, receive the ID transmitted from the IC card inserted in the IC cardholder (step S74). The communicating unit 31 b forming part of the certification apparatus 30 is operated to obtain, for example, the ID of the IC card 22 transmitted from the IC card 22 in step S74 in the case that the IC card 22 is inserted by the vehicle owner into the IC cardholder in step S71.

The certification unit 31 a forming part of the certification apparatus 30 is operated to judge whether or not the communicating unit 31 b has obtained the ID (step S75). When it is judged by the certification unit 31 a that the communicating unit 31 b has not obtained the ID in step S75, the control unit 31 is operated to have the red LED 32 b illuminate for three seconds to indicate an error message, and this process is terminated (step S76).

When, on the other hand, it is judged by the certification unit 31 a that the communicating unit 31 b has obtained the ID in step S75, the certification unit 31 a is operated to judge whether or not the IC card inserted in the IC cardholder is the first card , i.e., the IC card 22 on the basis of the ID obtained by the communicating unit 31 b and the ID stored in the internal storage unit 31 c (step S77). When it is judged by the certification unit 31 a that the IC card inserted in the IC cardholder is not the IC card 22 in step S77, the control unit 31 is operated to have the red LED 32 b illuminate for one second to indicate an error message, and this process is terminated (step S78).

When, on the other hand, it is judged by the certification unit 31 a that the IC card inserted in the IC cardholder is the IC card 22 in step S77, the certification unit 31 a is operated to certify the IC card 22 as being the authorized device (step S81), and the control unit 31 is operated to have the blue LED 32 a illuminate for one second (step S82).

The IC card 22 is then ejected by the user from the IC cardholder (step S83) and the IC card is inserted by the user into the IC cardholder within ten seconds (S84). The communicating unit 31 b is operated to transmit an ID request signal to the IC card (step S85), and, in return, receive the ID transmitted from the IC card inserted in the IC cardholder (step S86).

When, on the other hand, the IC card is not inserted into the IC cardholder within ten seconds after the IC card 22 is ejected from the IC cardholder in step S83, the control unit 31 is operated to have the red LED 32 b illuminate for three seconds to indicate an error message, and this process is terminated.

When the ID is transmitted from the IC card inserted in the IC cardholder in step S86, the certification unit 31 a forming part of the certification apparatus 30 is operated to judge whether or not the communicating unit 31 b has obtained the ID (step S87). When it is judged by the certification unit 31 a that the communicating unit 31 b has not obtained the ID in step S87, the control unit 31 is operated to have the red LED 32 b illuminate for three seconds to indicate an error message, and this process is terminated (step S88).

When, on the other hand, it is judged by the certification unit 31 a that the communicating unit 31 b has obtained the ID in step S87, the certification unit 31 a is operated to judge whether or not the ID obtained by the communicating unit 31 b is conformable to a predetermined format (S89). When it is judged by the certification unit 31 a that the ID obtained by the communicating unit 31 b is not conformable to the predetermined format, the control unit 31 is operated to have the red LED 32 b illuminate for three seconds to indicate an error message, and this process is terminated (step S90).

When, on the other hand, it is judged by the certification unit 31 a that the ID obtained by the communicating unit 31 b is conformable to the predetermined format, the certification apparatus 30 waits for an operation of the first switch 33 a and the second switch 33 b.

When the first switch 33 a and the second switch 33 b are operated by a user (step S91), the registering unit 31 d is operated to judge whether or not the first switch 33 a is turned on under the state that the second switch 33 b is turned on (step S92).

When it is judged by the registering unit 31 d that the first switch 33 a is not turned on under the state that the second switch 33 b is turned on in step S92, the control unit 31 is operated to have the red LED 32 b and the blue LED 32 a alternately illuminate at one-second intervals for six seconds to indicate an error message, and this process is terminated (step S93). When, on the other hand, it is judged by the registering unit 31 d that the first switch 33 a is turned on under the state that the second switch 33 b is turned on in step S92, the registering unit 31 d is operated to control the internal storage unit 31 c to have the internal storage unit 31 c store therein the ID of the IC card obtained by the communicating unit 31 b as being the ID of the second card (step S94).

This means that, in the certification apparatus 30, for example, the IC card 23 of the person authorized by the vehicle owner can be registered as the second card when the IC card 23 is inserted into the IC cardholder in step S84. In addition, more than one IC card can be registered as the second card after the processes shown in FIG. 3 are repeated by the user.

As described earlier, in the certification apparatus 30, in step S81, the certification unit 31 a is operated to certify whether or not the IC card is the authorized device on the basis of the ID of the IC card obtained by the communicating unit 31 b as being the first card in step S74 and the ID of the first card stored in the internal storage unit 31 c in step S64 (see FIG. 2). Accordingly, step 81 constitutes a certification step forming part of a certification method performed by the certification system 10.

Further, in the certification apparatus 30, in steps S74 and S86, the communicating unit 31 b is operated to obtain the ID transmitted from the IC card inserted in the IC cardholder. Accordingly, steps S74 and S86 constitute an obtaining step forming part of the certification method performed by the certification system 10.

Still further, in the certification apparatus 30, the registering unit 31 d is operated to control the internal storage unit 31 c to have the internal storage unit 31 c store therein the ID of the IC card 23 in step S94 obtained by the communicating unit 31 b in step S86 under the condition that the certification unit 31 a certifies the IC card 22 as being the first card in step S81. Accordingly, step S94 constitutes a storage step and a storage control step forming part of the certification method performed by the certification system 10.

In the certification apparatus 30, the IC card can be registered as the limited card after processes similar to those shown in FIG. 3 are carried out by the user. In addition, more than one IC card can be registered as the limited card after the processes similar to those shown in FIG. 3 are repeated by the user.

The description hereinlater will be directed to the operation of the certification system 10 in the case that the second card and the limited card are to be unregistered.

It is hereinlater assumed that the internal storage unit 31 c of the certification apparatus 30 stores therein the ID of, for example, the IC card 22 as being the ID of the first card before the second card and the limited card are unregistered, and the certification apparatus 30 comprises a central processing unit, hereinlater referred to simply as “CPU”, not shown, for controlling the whole processes in the certification apparatus 30.

The IC card is inserted into the IC cardholder by a user (step S101) and the second switch 33 b is held down by the user to assume an on-state uninterruptedly for three seconds (step S102) as will be clearly seen from FIG. 4. The communicating unit 31 b is operated to transmit an ID request signal to the IC card (step S103), and, in return, receive the ID transmitted from the IC card inserted in the IC cardholder (step S104). The communicating unit 31 b forming part of the certification apparatus 30 is operated to obtain the ID of, for example, the IC card 22 transmitted from the IC card 22 in step S104 in the case that the IC card 22 is inserted by the vehicle owner into the IC cardholder in step S101.

The certification unit 31 a forming part of the certification apparatus 30 is operated to judge whether or not the communicating unit 31 b has obtained the ID (step S105). When it is judged by the certification unit 31 a that the communicating unit 31 b has not obtained the ID in step S105, the control unit 31 is operated to have the red LED 32 b illuminate for three seconds to indicate an error message, and this process is terminated (step S106).

When, on the other hand, it is judged by the certification unit 31 a that the communicating unit 31 b has obtained the ID in step S105, the certification unit 31 a is operated to judge whether or not the IC card inserted in the IC cardholder is the first card , i.e., the IC card 22 on the basis of the ID obtained by the communicating unit 31 b and the ID stored in the internal storage unit 31 c (step S107). When it is judged by the certification unit 31 a that the IC card inserted in the IC cardholder is not the IC card 22 in step S107, the control unit 31 is operated to have the red LED 32 b illuminate for one second to indicate an error message, and this process is terminated (step S108).

When, on the other hand, it is judged by the certification unit 31 a that the IC card inserted in the IC cardholder is the IC card 22 in step S107, the certification unit 31 a is operated to certify the IC card 22 as being the authorized device (step S 111), and the control unit 31 is operated to have the blue LED 32 a illuminate for one second (step S112). The certification apparatus 30 waits for an operation of the first switch 33 a and the second switch 33 b.

When the first switch 33 a and the second switch 33 b are operated by a user (step S121), the registering unit 31 d is operated to judge whether or not the second switch 33 b is turned on under the state that the first switch 33 a is turned on (step S122).

When it is judged by the registering unit 31 d that the second switch 33 b is not turned on under the state that the first switch 33 a is turned on in step S122, the control unit 31 is operated to have the red LED 32 b and the blue LED 32 a alternately illuminate at one-second intervals for six seconds to indicate an error message, and this process is terminated (step S123). Likewise, when the IC card 22 is forcibly ejected by, for example, the user, while the certification apparatus 30 is waiting for the operation of the first and second switches after step S121, the control unit 31 is operated to have the red LED 32 b and the blue LED 32 a alternately illuminate at one-second intervals for six seconds to indicate an error message, and this process is terminated.

When, on the other hand, it is judged by the registering unit 31 d that the second switch 33 b is turned on under the state that the first switch 33 a is turned on in step S122, the registering unit 31 d is operated to delete all of the IDs of the second card and the limited card therefrom (step S124).

Thus, all of the second card and the limited card are unregistered from the certification system 10.

The description hereinlater will be directed to the operation of the certification system 10 in the case that the first card is to be unregistered, for example, after the vehicle owner is changed.

It is hereinlater assumed that the internal storage unit 31 c of the certification apparatus 30 stores therein the ID of, for example, the IC card 22 as being the ID of the first card before the first card is unregistered, and the certification apparatus 30 comprises a central processing unit, hereinlater referred to simply as “CPU”, not shown, for controlling the whole processes in the certification apparatus 30. Further, it is hereinlater assumed that neither the second card nor the limited card is registered with the certification apparatus 30 resulting from the fact that the first card can be unregistered from the certification apparatus 30 only under the state that neither the second card nor the limited card is registered.

The certification apparatus 30 is operated to control the internal storage unit 31 c to have the internal storage unit 31 c delete the ID of the first card, i.e., the IC card 22, therefrom after processes similar to those shown in FIG. 4 are carried out by the user under the condition that neither the second card nor the limited card is registered.

After the ID of the IC card 22 is deleted from the internal storage unit 31 c, no first card is enabled in the authorization system 1, and thus the master card 21 becomes the authorized device again. This means that when the ID of the first card, i.e., the IC card 22 is deleted from the internal storage unit 31 c, the ID of the master card 21 is restored in the internal storage unit 31 c, and thus the master card 21 becomes enabled again. The ID of the master card 21 is stored in a storage unit, not shown, other then the internal storage unit 31 c after the registering unit 31 d controls the internal storage unit 31 c to have the internal storage unit 31 c delete the ID of the master card 21 therefrom so that the ID of the master card 21 can be later restored in the internal storage unit 31 c. The certification system 10 can register the IC card other than the IC card 22 as the first card, after the processes shown in FIG. 2 are carried out by the user while the master card 21 is enabled.

The information transmitting unit 31 e forming part of the certification apparatus 30 is operative to transmit the ID of the first card to be deleted from the internal storage unit 31 c to the exterior thereof, viz., the Land Transportation Office when the ID of the first card is deleted from the internal storage unit 31 c. This leads to the fact that the certification apparatus 30 can improve the operational efficiency of the Land Transportation Office in terms of registering vehicles.

Form the foregoing description, it is to be understood that the certification system 10 thus constructed can prevent the other IC card from being registered as an additional first card using the master card 21 without the knowledge of the owner of the first card resulting from the fact that the master card 21 cannot be certified as being the authorized device while at least one IC card is certified as being the first card. Further, the certification system 10 can prevent the other IC card from being registered as an additional second card without the knowledge of the owner of the first card resulting from the fact that the other IC card cannot be certified as being the second card or the limited card unless the IC card is in advance certified as being the first card. This leads to the fact that the certification system 10 can enhance the security in using the vehicle.

Still further, the certification system 10 can provide different level of security depending on the user of the vehicle, resulting from the fact that vehicle-mounted components which the first card is authorized to use include one or more vehicle-mounted components other than the vehicle-mounted components which the limited card is authorized to use. The certification system 10 thus constructed can improve convenience in using the vehicle. As described in the above, in the certification system 10, the first card as well as the limited card may be authorized to, for example, unlock the door lock and start the engine while, on the other hand, only the first card is authorized to unlock the glove box lock and the trunk lock, and the limited card is not authorized to unlock the glove box lock and the trunk lock. The certification system 10 thus constructed makes it possible for the vehicle owner to have, for example, an employee at a hotel or a restaurant, use the limited card to move the vehicle while the glove box and the trunk are securely locked.

Yet further, the certification system 10 can prevent the IC card certified as the second card or the limited card from being unregistered without the knowledge of the owner of the first card resulting from the fact that the second card or the limited card cannot be unregistered unless the IC card is in advance certified as being the first card. This leads to the fact that the certification system 10 can enhance the security in using the vehicle.

Further the more, the certification system 10 can prevent the IC card certified as the first card from being unregistered without the knowledge of the owner of the first card resulting from the fact that the first card cannot be unregistered unless the IC card is in advance certified as being the first card. This leads to the fact that the certification system 10 can enhance the security in using the vehicle. In addition, the certification system 10 can prevent the second card or the limited card from remaining enabled without the knowledge of the owner of the first card resulting from the fact that the first card cannot be unregistered unless the second card or the limited card is in advance unregistered. This leads to the fact that the certification system 10 can enhance the security in using the vehicle.

In the certification system 10, the IC card 22 may be constituted by a driving license. The certification system 10 can improve convenience in using the vehicle in the case that the IC card is constituted by a driving license in comparison with the case that the IC card 22 is provided separately from the driving license, resulting from the fact that the vehicle owner does not need to have additional IC card other then the driving license. Likewise, in the certification system 10, the IC card 23 may be constituted by a driving license.

Although it has been described in the above that any one of the IC card 22 and the IC card 23 forming part of the certification system 10 may be registered as the first card or the second card as well as the limited card, it is needless to mention that the IC card to be registered only as the limited card may be provided separately from the IC card to be registered as the first card or the second card.

As will be seen from the foregoing description, it is to be understood that the certification system according to the present invention has an effect of enhancing the security and available for a system using an IC card.
